I've not played a lot online - maybe ~50-75 races - but I've not experienced any significant lag at all in regional matches (haven't tried global). I see these complaints and mentions of de-sync etc., but it's very often closely related to the user's internet conection and/or playing global matches.

That's not to say it's perfect, and it certainly isn't feature rich, but I wouldn't call it broken at all.

i am mostly a Pc gamer and am not used to such crazy lag.

I would identify myself very similarly, but (a) the "crazy" (and presumably frequent?) lag seems like hyperbole given that it's not a game that requires the same level of precise sync of a shooter (for ex) so you really ought to not notice that much, and (b) my general experiences on PC have seldom been much better (ie. Very good overall, but occasional issues).

If you really find you're having issues even when playing only regionally in MK8 (but various PC games are fine), it may be worth investing in an ethernet adapter as the source may be your wireless connection (either on the WiiUs end or the router).

Holy shit you're ignorant lol. Mario kart has it's own racing style that I enjoy. I enjoy the wacky tracks and the drifting. I don't see why you're hating so much on a no item mode? Like if you love the RNG aspect, you can play with items. But some of us get sick of it, it would be a fun alternative. And with smash bros, do you ever watch twitch streams of it? Did you even hear about the new smashs bros? The ranked mode has items disabled...maybe you should tell nintendo to make ranked open up Tekken, cause apparently you're all knowing and only your opinion matters.

Items are great, I never said they aren't good. I really enjoy how they can affect a race or a smash bros fight. But it would be nice to have another mode, just when you don't want items...That's why smash let's you turn it off...I don't get why people here are SOOOO defensive over items lol. If you want them, don't play the no item mode, simple!
